Meh, I don't know what the hell this is so I'm going to post it and run the math to show how -EV it was, and hopefully this analysis will train me not to do this again.

PokerStars No-Limit Hold'em, $0.50 BB (8 handed) - Poker-Stars Converter Tool from FlopTurnRiver.com

Hero (MP1) ($50)
MP2 ($55.85)
CO ($22.50)
Button ($50)
SB ($55.65)
BB ($59.95)
UTG ($50)
UTG+1 ($54.05)

Preflop: Hero is MP1 with A, A
2 folds, Hero bets $2, 3 folds, SB calls $1.75, 1 fold

Flop: ($4.50) 3, 9, 8 (2 players)
SB checks, Hero bets $3.50, SB raises to $11, Hero raises to $48 (All-In),

Villain is a 13/10 reg, pretty aggro. I have a note on him saying he 2 barrelled AK vs me on a board like 2546 or something.

I think his range for check raising is this:

equity win tie pots won pots tied
Hand 0: 40.743% 40.74% 00.00% 6857 0.00 { AcAh }
Hand 1: 59.257% 59.26% 00.00% 9973 0.00 { QQ, 99-88, 33, JdTd, 7d6d }

I included QQ in there just to put in 6 overpair combos in case he may decide to c/r with them. Without an overpair in there though it is interesting to note his range is crushing us with like 80% equity or something. If we just call and the turn bricks he still has us mega crushed. Clearly he isn't folding a better hand, and we certainly aren't shoving for value, thus, shoving is in fact a mistake. The correct play here would be to Bet/Fold.

Okay now time to do it right while playing.
